武汉城市圈城镇体系空间分形研究

Spatial Fractal Research on the Town System of Wuhan Metropolitan

基于统计学和分形理论,对武汉城市圈城镇体系的城镇规模级别分布维数、空间关联维数、空间集聚维数等分形维进行计算与分析。3项指标的相关系数都较高,武汉城市圈城镇体系空间自组织现象明显,存在空间分形结构和分形特征;武汉城市圈城镇体系具有规模分布较均衡、城市分布交通指向性明显、城市空间关联较弱、城镇体系内各城市向中心城市高度集聚等基本规律与特征。针对所存在的主要问题,最后提出武汉城市圈城镇体系相关的优化调控措施。

Based on the statistics and fractal theory, the values of the fractal dimensions, including the scale distribution dimension, spatial correlation dimension and spatial gathering dimension of the town system of Wuhan Metropolitan were calculated and analyzed. As was revealed by the research, the major regularity and character of the town system was shown as follows： the city scale is well distributed to some extent, the distribution of cities ap- parently depended on traffic lines, the spatial correlation among cities was relatively slight and they significantly gathered to the central city as well. Further more, the main exiting problems were found, and at last, countermeasures on promoting the regulation on the town system of W.uhan Metropolitan were put forward pointedly.
